New Delhi: Prime Minister Manmohan Singh's visit to Japan was cancelled on Wednesday - a day before he was scheduled to leave. An MEA official said the tour was put off due to an internal development in Japan. He is, however, keeping his Cambodia visit plan intact.

"On November 2 we had announced about the PM's visit to Japan. Due to some internal developments in Japan, the summit has been postponed. There may be declaration of elections in Japan in the coming days. Japan's embassies are in touch for a convenient date for his visit," said MEA official Syed Akbaruddin.

Japanese Prime Minister Yoshihiko Noda on Wednesday said that he was open to dissolving the lower house of parliament on November 16 and to hold elections in December if the opposition agreed to pass reforms to the electoral system.
